Deploying a Smart Contract to the Bitfinity EVM: A Step-by-Step Guide

Smart contract deployment on the Bitfinity EVM combines Ethereum's flexibility with Bitcoin's security. This comprehensive guide walks you through the entire process while highlighting best practices for developers.

Getting Started with Bitfinity EVM Development

Step 1: Selecting an IDE and Framework

Choosing the right development environment is crucial for efficient smart contract creation:

• Remix IDE: Browser-based Solidity IDE with built-in compiler and debugger
• HardHat: JavaScript development environment offering advanced testing capabilities
• Truffle Suite: Comprehensive framework for Ethereum-like blockchain development

👉 Compare development frameworks to find your ideal workflow

Pro Tip:
Always use Solidity linters like Solhint to catch syntax errors and security vulnerabilities early in your development cycle.

Step 2: Wallet Configuration

MetaMask remains the most popular wallet for EVM interactions:

1. Install the MetaMask browser extension
2. Create or import an Ethereum-compatible wallet

3. Configure Bitfinity network settings:

   • RPC URL: https://testnet.bitfinity.network
   • Chain ID: 355113
   • Symbol: BTF

Step 3: Network Selection

Bitfinity offers multiple deployment environments:

Key Consideration:
Always deploy and test thoroughly on Testnet before Mainnet deployment.

Step 4: Smart Contract Development

Here's a basic Solidity contract example:

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.26;

contract SimpleStorage {
    uint256 public storedData;
    
    function set(uint256 x) public {
        storedData = x;
    }
    
    function get() public view returns (uint256) {
        return storedData;
    }
}

Contract Essentials:

• Always specify SPDX license identifier
• Use explicit Solidity version pragma
• Include clear function visibility declarations

Step 5: Gas Management

Understanding gas costs is vital for successful deployments:

• Testnet: Use faucet to obtain BTF tokens
• Mainnet: Acquire BTF through exchanges
• Estimate gas using eth_estimateGas RPC call

👉 Learn gas optimization techniques for cost-efficient contracts

Step 6: Deployment Verification

Post-deployment steps:

1. Retrieve contract address from your deployment tool
2. Verify source code on Bitfinity Block Explorer
3. Confirm bytecode matches your compiled contract

Verification benefits:

• Transparency for users
• Enables direct contract interaction
• Builds trust in your dApp

Step 7: Contract Interaction Methods

Multiple ways to engage with deployed contracts:

1. Direct via Block Explorer
2. Programmatic using ethers.js/web3.js
3. Through dApp interfaces

Example ethers.js interaction:

const contract = new ethers.Contract(
  '0xYourContractAddress',
  ['function get() view returns (uint256)'],
  provider
);

const value = await contract.get();

Advanced Development Concepts

Security Best Practices

1. Use OpenZeppelin's audited contracts
2. Implement reentrancy guards
3. Conduct thorough unit testing
4. Consider professional audits for valuable contracts

Upgrade Patterns

Proxy contracts enable upgradability while maintaining immutability:

1. Deploy proxy contract pointing to logic contract
2. Store all state in proxy
3. Upgrade by deploying new logic contract and updating proxy reference
